Additional information

Hydrolysis: 

In accordance with REACH Annex XI, the "Hydrolysis as a function of pH" does not need to be conducted as the test is scientifically unjustified respective technically not feasable. The guanidine ion is expected to have such a long hydrolysis half-life at environmentally relevant pH that the measurement is not feasable. This is concluded from abiotic biodegradation control with river water (Mitchel, Chemosphere, 1987).

  

Photodegradation

Due to the low vapour pressure the substance under investigation will not be present in the gas phase in the atmosphere in appreciable amounts and therefore the elimination path photodegradation in air will be only of minor importance.
